Remarks
The array of Material CRC values is returned by RayTracingAccelerationStructure.CullInstances in RayTracingInstanceCullingResults.
The cost for enabling this flag depends on how complex the Materials are and how many different Materials are used in a Scene. The CRC array can be used for example to reset the convergence during path tracing if a Material property has changed between frames.
